I miss a completely frontal shot, taken from a building in front without having to point the camera upwards, which would give the photo a more balanced feel.

Not necessarily, but I am not in a position to argue. I will only note that balconies are not always located on the first floor, but when the balcony is located, for example, on the 5th-6th floor (and the height of each apartment is not 2.5 meters according to the principles of Le Corbusier, but more, 3-4 meters), and a street of average width -> even the telephoto does not save from distortion. It is technically impossible to "look" at the balcony through the camera from the front. Sometimes this is prevented by some other reasons.

I have other photos of balconies, a small part can be considered as frontal, like this one:

_{Canon 350D + Canon 70-300mm | f 5.6 | t 1/100 | ISO 100 | ex-jpg}

(had to erase it from the post due to '4 pictures' restriction).
Will definitely select strictly frontal captures next time.
